Restrictions and Cautions
Please use pps mode when doing storm suppression, because it is inaccurate in ratio mode
There will some routes in garbage state which can not be deleted when heavy route
protocal packets injected into an interface which up and down with high frequency
Can not reach line-rate for full ports in XRN mode
The system default anti-attack function may be affected if the queue-schedule is changed.
Please leave queue-schedule unchanged if there is no special requirement
IGMP snooping is not supported on 10G expansion subslot
Silicon behaviour: giant packets and CRC packet can not be counted accurately on 10G
expansion subslot
Silicon behaviour: the IP packets with option field can not be forwarded
There is a limitation of flow-control, 5500G-EI can only process receiving pause frame, it
can not send out pause frame
Only the MAC address existed in the master unit will be displayed when “display mac-
address”. The MAC address on expansion subslot and slave unit will not be displayed.
Only support psftp client of a third-party software named putty when 5500G-EI is used as
SSH Server
Try to avoid powering off the device when executing the commands like save which include
writing Flash operation.
Please add 4 bytes more for the length of inner VLAN tag when calculating offset of user
defined ACL, because the chip treats all packets as double tagged.
BGP does not support ECMP.
Please don’t upgrade the expansion card Bootrom until the newer version (larger than 220)
expansion card Bootrom is released.
Limitation of port mirroring: The packets sent by CPU cannot be mirrored on egress port.
When you mirror packets sent by ports on an expansion module, the packets from a port on
the front panel to the expansion module cannot be mirrored if the monitor port is not on the
expansion module.
3COM OS Switch 5500G V3.03.02 Release Notes
March 19, 2009 Page 9 of 47
Do not use vlan-mapping with voice vlan , 802.1x, mac authentication, port-security, mac-
max-count ,which is strongly suggested.
An inexistent destination VLAN could be configured in mac-address-mapping, and the
corresponding MAC replication in the VLAN is actually done.
ARP Inspection, IP source guard features do not support link-aggregation ports.
DHCP snooping can't work together with QinQ.
When mac-address-mapping and link-aggregation are needed to work on the same port,
please configure mac-address-mapping first, then configure link-aggregation; while when
removing mac-address-mapping, please remove link-aggregation first. When there are lots of
MAC addresses needed to be mapped, please do not do shutdown and undo shutdown
operation frequently.
The destination MAC address for smartlink is 01-0f-e2-00-00-04.
Notice about NTP configuration in stacked devices
For stacked devices including NTP configuration, when upgrading the software from version between
V3.03.00 and V3.03.01p05 (V3.03.01p05 is excluded) to V3.03.02 or newer version, the NTP
configuration should be removed firstly then re-configured after stacking reboot.

March 19, 2009 Page 11 of 47
Features Description
Port internal loop/external loop tests
The tests provide means to online detect port faults, the internal loop test is used to diagnose the physical channels between switch chips and PHY chips; the external loop test is used to diagnose the physical channels between PHY chips and network interfaces with the help of self-loop header. The two tests used together can distinguish whether a fault is a switch fault or a link fault.
Loopback detection
Voice vlan The voice VLAN feature is able to add ports into voice VLANs by identifying the source MAC addresses of packets. It automatically assigns priority rules, ensures that voice traffic takes appropriate priority so as to ensure the voice quality. This feature supports two application modes: manual and automatic.
Unicast, multicast and broadcast packets suppression
Configured based on ports
Supporting suppression by bandwidth ratio and suppression by pps (packets per second)
broadcast suppression global configuration
802.1X authentication The main purpose of the IEEE 802.1x protocol is to implement authentication for wireless LAN users. But its application in LANs defined by IEEE 802 LAN standards provides a method of authentication for LAN users.
Centralized MAC address authentication
Centralized MAC address authentication is triggered by users' data packets. In this authentication, users' MAC addresses are used as both user names and passwords. Upon receiving the first packet from a user, the switch retrieves the source MAC address from the packet, adds the address to both user name and password fields in a radius packet, and sends the radius packet (authentication packet) to a radius server. The remaining processing procedure is similar to 802.1x. If the password authentication on the server passes, the source MAC address is added to the MAC address table on the switch, and the user is permitted to access the network.
table full traps when table is full, the trap will be sent for mac/arp /routing table
Guest VLAN Before authentication or after authentication failure, it can access the resource of guest vlan Guest vlan for 802.1x
IP+MAC+PORT binding
Port security support multiple mode for port security
SSHv2
TACACS+ Tacacs+ feature is improved based on the standard RFC1492, it can implement multiple AAA authentication via Server-Client mode. This function is more security than Radius. only support single unit
3COM OS Switch 5500G V3.03.02 Release Notes
March 19, 2009 Page 12 of 47
Features Description
Password control Password control feature is focused on the password ageing management. When a user enters a switch, the switch will tell him how many days the password will be expired. If the password is not expired the switch will says the remainder days and allow user to modify the password. When the user sets the new password, the switch will record the new code and creation time and date. If the user does not modify the password he can use the old password to access the switch;
When the password is expired, the switch will inform user about this case and a new password must be entered and confirmed. If the password is illegal and the twice confirmations fail, the user must re-enter the password.

Unknown multicast drop
IGMP proxy
IGMP SNOOPING IGMP Snooping (Internet group management protocol snooping) is a multicast control mechanism operating on Layer 2 Ethernet switches, which is used to manage and control multicast groups.
VRRP
DHCP server embedded dhcp serve
3COM OS Switch 5500G V3.03.02 Release Notes
March 19, 2009 Page 13 of 47
Features Description
Dhcp-relay The earlier DHCP protocol only applies to the circumstances that DHCP clients and DHCP servers are in the same subnet and cannot operate across network segments. Therefore, to implement dynamic host address assignment, each subnet should be deployed with a DHCP server. This is obviously uneconomical.
DHCP Relay is introduced to resolve this problem. Through a DHCP relay, DHCP clients in a LAN can communicate with a DHCP server in another subnet to obtain valid IP addresses. In this way, DHCP clients in multiple networks can share one DHCP server. This saves costs and helps to implement centralized management.
DHCP snooping snoop dhcp packets in layer2 mode
Fake dhcp server detection
Fake dhcp server detection in dhcp relay
IP routing Static routes
RIP(Routing Information Protocol )
RIP support ECMP
OSPF
BGP
NTP Along with the ever growing of network complicity, clock synchronization between the devices in a network becomes more and more important. NTP (network time protocol), a protocol built on top of TCP/IP, is used to distribute accurate time in a network.

Diagnostics and alarm output
When a switch operates, hardware/software problems may occur; quickly recording and reporting problems is important for troubleshooting the problems.
Fast startup Both fast and normal start settings are supported.
In fast start mode, the switch can start up within 60 seconds. This greatly increases the startup speed in comparison with previous switches
When starting in fast mode, the switch skips the POST (power-on self-test) and runs the APP application directly.
When starting in normal mode, the switch performs the whole POST.
You can set the start mode to fast or normal by using the Boot ROM menu.

Configuration Changes
V3.03.02 Changes in Operations
1) Change to VLAN interface number
VLAN interface number is enlarged from 64 to 128
V3.03.01p05 Changes in Operations
1) Change to static route number
The maximum supported static route number on device is changed from 256 to 1024.
V3.03.01p03 Changes in Operations
1) Modification about dot1x timer tx-period command
Before Modification:
The range of 802.1x multicast request packet transfer period set by dot1x timer tx-period command is
10-120 seconds. Based on the rule that port will enter guest VLAN when 1 such packet get no
response, the shortest time for entering guest VLAN is about 10 seconds.
After Modification:
The range of 802.1x multicast request packet transfer period set by dot1x timer tx-period command is
1-120 seconds. Based on the rule that port will enter guest VLAN when 1 such packet get no
response, the shortest time for entering guest VLAN is about 1 seconds.
2) Change to loopback-detection function
A new choice "shutdown" is added to loopback-detection function. If loopback-detection shutdown is
enabled and there is a loop under a port, the port will be shutdown. User can restore the port to UP
state with command "undo shutdown". If a port is shutdown by loopback-detection, command "display
interface" indicates the port is in "LOOPBACK DETECTION DOWN" state, and "display brief
interface" shows that the port is in "LPD DOWN" state.
Note:
a) Loopback-detection shutdown is different from command line "shutdown" in some degree.
If a port is shutdown by loopback-detection function, user can't see command "shutdown"
by running "display this" under that port.
b) Loopback-detection shutdown function is mutually exclusive with loopback-detection
control function.
V3.03.01p01 Changes in Operations
1) Change to 802.1x function
In early version:
a) The 802.1x client passes the authentication. If the client changes its IP address, the switch will
make the client log off.
b) The 802.1x client passes the authentication. If the client changes its IP address by using DHCP
and the switch does not enable DHCP-Snooping function, the switch will make the client log off.
3COM OS Switch 5500G V3.03.02 Release Notes
March 19, 2009 Page 23 of 47
c) The 802.1x client passes the authentication. If the client changes its IP address by using DHCP
and the switch enable DHCP-Snooping function, the switch will not make the client log off.
In current version:
The switch will not make the client log off when all the above mentioned three situations occur.
V3.03.00 Changes in Operations
1) info-center buildrun on the last configuration
2) Canceling the restriction for vlan-vpn coexisting with other protocols such as STP/GVRP.
3) the device as a tftp client can compatible with "\r\n" and"\n" wrap prompt, so we can upload or
download files correctly with tftp server on UNIX system
4) Optimizing the ping performance, so the counter statistics are affected. The counter statistics is
not as real-time as old version
5) User can configure port mirror function by web
6) A device will forward the unknow 1x EAP type packets
7) The default DLDP interval time is changed to 5s, and the range is 1s~100s, in the previous
versions, the interval time is 10s, and the range is 5s~100s. the DLDP cannot work with different
interval time, user should modify the interval time to the same value.
8) DLDP protocol number changed from 0800 to 8809, when V3.03.00 or later version work with
V3.02.04 or earlier version, when the DLDP port stp status is discarding, the DLDP cannot
function normally.
9) The matching sequence for web file is changed to default, main, backup, while before the
sequence is main, backup, default.
10) The max sub ip number is changed from 4 to 6.
11) The combo support physical shutdown: the “shutdown” operation on active combo port make the
port down physically and do not used to switch the combo status between active and inactive;
only “undo shutdown” operation is used to switch the status.
12) Do not send PortMstiStateDiscarding trap and log when port status changed from up to down.
